New releases of P5 required an update of the schema, which I've now done, generating the new schema from ROMA. ROMA is still a little flaky; it seems to delete information almost randomly from the project description (especially info inside tags), and it also displayed only the appInfo tag as a customized addition, rather than both appInfo and appDetail. However, when I generated the schema, it seemed to include appDetail, and files validate against the new schema.

IMT will need a new release soon, for this and the VISTA updates, but we'll wait until Transformer gets finished (there are a couple of tweaks to do on that), and release both on the same day.
